A new distributed channel assignment scheme is described, called unsupervised FDMA (UFDMA) which makes use of a coexistence etiquette. The techniques required to model a UFDMA communications protocol using a commercial modelling tool are presented, including a description of how the protocol is configured using the tool's modelling hierarchy. Time dependent results can be obtained from the tool since parallel execution is emulated by time stamping each event. Channel usage results are presented from the simulations which show that the channel assignment algorithm successfully chooses empty channels. The call set up time, SNR, and transmitter power statistics are also included to illustrate the ease in which specific results can be obtained from the tool.
